Retention Indices for Frequently Reported Compounds of Plant Essential Oils
Retention Indices for Frequently Reported Compounds of Plant Essential Oils V. I. Babushok,a) P. J. Linstrom, and I. G. Zenkevichb) National Institute of Standards and Technology, Gaithersburg, Maryland 20899, USA (Received 1 August 2011; accepted 27 September 2011; published online 29 November 2011) Gas chromatographic retention indices were evaluated for 505 frequently reported plant essential oil components using a large retention index database. Retention data are presented for three types of commonly used stationary phases: dimethyl silicone (nonpolar), dimethyl sili- cone with 5% phenyl groups (slightly polar), and polyethylene glycol (polar) stationary phases. The evaluations are based on the treatment of multiple measurements with the number of data records ranging from about 5 to 800 per compound. Data analysis was limited to temperature programmed conditions. The data reported include the average and median values of retention index with standard deviations and confidence intervals.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract The tree of Litsea cubeba is widely spread in China, Indonesia and other part of Southeast Asia. The essential oil of Litsea cubeba (EOLC) is obtained by steam distillation from the pepper-like fruits tree Litsea cubeba. The EOLC consists of about 29 active compounds. Among them, citral is the main component; the content of citral is nearly 80% of the EOLC. Due to the special function group, citral is easy to react with many chemicals. Thus, EOLC is usually applied as starting ma- terial to carry out aldol condensation, reduction, and six-member ring forming reaction. The EOLC is extensively employed to synthesis of geranal nitriles, pseudonoe, ionone, methyl ionone, Vita- min E and Vitamin A. These products are broadly applied in the fields of fragrance, perfume, med- icine and so on. This paper presents comprehensive utilization of EOLC as raw materials to syn- thesize many active chemicals. Keywords Litsea cubeba, Essential Oil, Citral, Synthesis 1. -

Degradation of Tocopherol and Tocopheryl Acetate by Ruminal Contents in Vitro
DEGRADATION OF TOCOPHEROL AND TOCOPHERYL ACETATE BY RUMINAL CONTENTS IN VITRO 1999 Animal Science Research Report Pages 119-125 Authors: Story in Brief H. Han and F. N. Ruminal fluid, from ruminally cannulated beef steers (300kg) fed a Owens concentrate or a high roughage diet, was used to measure disappearance of α -tocopherol and hydrolysis of α -tocopheryl acetate to α -tocopherol in vitro. Undiluted ruminal fluid was used in Exp. 1, while buffer was added in Exp. 2. Degradation of α -tocopherol or conversion of α -tocopheryl acetate into α -tocopherol was estimated after 12 and 24 h incubation of each α - tocopherol in ruminal fluid. Following 24 h incubation in ruminal fluid, the α -tocopherol concentration in ruminal fluid was not changed in either Exp. 1 or Exp. 2 by α -tocopherol or tocopheryl acetate. These results suggest that α -tocopherol is not destroyed in the rumen and that α -tocopheryl acetate was not extensively changed into α -tocopherol by ruminal microbes. Key Words: In vitro, Rumen, Vitamin E, Destruction Introduction Most studies of bioavailability of vitamin E have monitored responses in the blood or tissue α -tocopherol concentration. Such studies have been reported for ruminants (Njeru et al., 1995; Hidiroglou et al., 1992), swine (Chung et al., 1992) and horses (Siciliano et al., 1997). Based on those studies, d-α -tocopherol has a higher bioavailability than other forms of vitamin E. Because the acetate form is less susceptible to oxidative destruction, α -tocopheryl acetate is used widely in the feed industry as a source of vitamin E. -

Zelinsky Institute of Organic Chemistry Russian Academy of Sciences, Leninsky prospect 47, Moscow 119991, Russia * Correspondence: [email protected] Received: 16 August 2018; Accepted: 17 September 2018; Published: 24 September 2018 Abstract: Recent progress in the leading synthetic applications of acetylene is discussed from the prospect of rapid development and novel opportunities. A diversity of reactions involving the acetylene molecule to carry out vinylation processes, cross-coupling reactions, synthesis of substituted alkynes, preparation of heterocycles and the construction of a number of functionalized molecules with different levels of molecular complexity were recently studied. Of particular importance is the utilization of acetylene in the synthesis of pharmaceutical substances and drugs. The increasing interest in acetylene and its involvement in organic transformations highlights a fascinating renaissance of this simplest alkyne molecule. Keywords: acetylene; vinylation; cross-coupling; addition reactions; drugs; pharmaceutical substances; biologically active molecule; monomers; polymers 1. Introduction Since the discovery of acetylene, new areas of acetylene chemistry have been continuously developed. The rich scope of chemical transformations available for a C≡C triple bond can be exemplified by coupling [1–5] and addition reactions [6,7]. -
